Primary finding
Probable cause
The pilot’s failure to maintain directional control of the airplane while landing on a snow-covered unimproved runway.
Investigator assessment
Analysis narrative
The pilot reported that he attempted a touch and go landing on a snow-covered backcountry airstrip, in the tailwheel-equipped airplane. The snow was deeper than he anticipated and the ground beneath the snow softer than expected. During the landing, the main wheels dug in, and the airplane nosed over. The vertical stabilizer and rudder were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
